No, I haven't.. but there are 2 on top of homes right next door to me. The one guy has his on his 1st level roof, said he had some "jitters" during a windy storm (lots of trees that could have caused this). The other guy, had it for 3 years said he's never had anything go wrong except when his tuner failed. I'm sure that short of a flock of 747's flying over or some squirrel parking is big fat butt in front of the LNB device, signal dropouts seem to be few if not far far between. Heck, I'm sure it's more reliable then my VoIP service I had with plutorocket (aka sunrocket).
